The White House said Friday that an unknown "high-altitude object" had been shot down over the waters off Alaska.
Responding to reporters' shouted questions about the shootdown Friday afternoon outside the White House, Biden called the operation a "success.".
It comes just days after the U.S. shot down a Chinese surveillance balloon last Saturday, following a political firestorm.
Kirby said the object was about the size of a small car and was at flying about 40,000 feet.
It was described as "cylindrical and silver-ish gray" and seemed to be floating, a U.S. official said.
"It came in, inside our territorial waters, those waters right now are frozen, but inside territorial airspace and over territorial waters.
